Patented July 13, 1915 Application filed December 29, 1913. Serial No. 809,253.

To all whom it may concern Be it known that I, l/VALTON D. WOOLLEY, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Entrance-Fittings or Pipe-Caps for Electric-Service Pipes or Conduits, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof, in which Figure l is an elevational view of my new entrance fitting or pipe cap operatively mounted upon a vertically-disposed electric service pipe or conduit; Fig. 2 is a vertical sectional view through the same and said conduit or pipe; Fig. 3 is a vertical sectional view through my new entrance-fitting ,or pipe-cap operatively mounted upon a horizontally-disposed conduit or pipe, the conduit or pipe being shown in longitudinal section; Fig. 4 is an inverted plan view, reference being had to Figs. 1 and 2, of my new entrance-fitting or pipecap, the pipe or conduit being shown in transverse section; Fig. 5 is an inverted plan view of the main or body-member of my new entrance-fitting or pipe-cap; and Fig. 6 is approximately a rront elevational View of my new entrancefitting or pipe-cap with the main or bodymember thereof in section on the line 6-6, Fig. 2.

This invention relates to certain new and useful improvements in entrance-fittings or pipe-caps for electric service pipes or conduits. As is well known, the electric service wires for a building or structure usually enter or lead into the building from the main service lines through a short horizontallydisposed pipe or conduit which, at the convenience of the builder, is generally arranged in the wall of the building at a point either below, or at some distance above, the surface of the ground. In the former case, however, there is usually connected at one end by means of an elbow-joint or the like to the projecting outer end of the short horizontally-disposed pipe a vertically-disposed pipe .or conduit into and through which the said wires are led to said horizontally-disposed pipe or conduit, this vertically-disposed conduit or stand-pipe being arranged closely adjacent the outer face of the wall of the building and having a length r The principalobiec't of my inventionis,

therefore, to provide a device or pipe-cap which may be readily interchangeably emploved or used in connection with, and by which the electricservicewires may be held separated from one another ongoing into, or coming out of, either a horizontally-disposed conduit or pipe or a vertically-disposed conduit or pipe for electric service wires.

Qther'objects of my invention are to provide a device of the kind described of simple and inexpensive construction and of few, durable, and separable parts which may with ease be operatively detachably secured together; to provide a deviceof the kind described through which several electric wires may be conveniently led separated and insulated from one another and which may be quicklyand with facility operatively mounted or arranged upon the service conduit or pipe, and to improve generally upon de vices of the class stated.

With the above and other objects in view, my invention resides in certain novel features of form, construction, arrangement, and combination of parts, all as will hereinafterbe described and afterward pointed out in the claims.

As shown in the accompanying drawings, in which like reference characters refer to like parts throughout the several views, my new entrance-fitting or pipe-cap comprises substantially three cooperating and separable parts or members, namely, a bodymember A, which ispreferably of-suitable metal and inone piece, a member B, which is preferably of porcelain or other suitable insulation material, provided lengthwise thereof with preferably a plurality or row of perforated bosses or small tubular extensions or outlets I) through which wires W may be passed or extend, and a plate-member C, which is also preferably of suitable metal, provided centrally wlth a tubular extension projecting therefrom at an angle of Member A, which is preferably open at 1ts front and rear sides, has preferably three sides or walls, a convexed, somewhat or approximately arc-shaped main wall 1 and side walls 22 aproximately of segmental shape in outline, walls 2-2 at their curved or arc-shaped end merging into wall 1 preferably in a gentle curve or rounded corner, as at a, Fig. l, and at their other or upper and forward ends being straight and flush, respectively, with the front and rear ends of wall 1. Wall 1 and side walls 2+2 at their front and upper ends, respectively, are inturned to provide a continuous, substantially widened U-shaped flange 8; and formed or provided on'the inner face of side walls 2 2 and extending approximately parallel with the legs of Ushaped flange 3, are inwardly-projecting ribs 4, flange 3 and ribs at forming a slide-way interiorly of member A in which porcelain member B is adapted to removably operatively fit with its said perforated bosses I) presented outwardly and with flange 3 overlying and protecting marginal portions thereof, as seen clearly in Fig. 4., member B, when in such position, providing a closure for the open front side of body-member A.

W all 1 and side walls 22 at their rear and forward ends, respectively, are somewhat offset outwardly, as at 5, to provide preferably continuously ther earound, as seen in Fig. 5, an interior shoulder, as at 6, which is adapted to afford seat on member A for plate-member C, plate-member C being adapted, when in either of its reversible operative positions relatively to members A and B, reference being had to Figs. 2 and 3, to provide a closure for the open rear side of body-member .A and fit within member A with its tubular extension 0 presented outwardly and its outer face substantially flush with the outer faces of the rear and forward ends of said wall 1 and side walls 22 of member A, as seen clearly in Fig. 4.

Preferably integral with member Cis a pair of oppositely-disposed outwardly-extending ears 77, which are adapted to match or coincide with a pair of substantially similar ears S8 preferably integral with side-walls 2---2 of member A, ears 7( and 8-8 being perforated to receive bolts 9 or other fastening means, whereby member C may be detachably and separably secured operativelv to member A in either of its reversible p6.- sitions relatively thereto, member C, as will be seen, being adapted to reversibly or interchangeably fit in the seat provided therefor in member A, so that its said tubular extension 0 may be either rearwardly or for wardly angularly disposed relatively to said tubular extensions 6 of member B.

Should it be desired to employ my new pipe-cap or fitting on a vertically-disposed service conduit or standpipe, as, for instance, pipe or conduit P, see Figs. 1 and 2, then plate-member C and member A are detachably fastened together, as described, member B being operatively in its said slideway and wires WV having been led. or passed through said outlets or perforated bosses b of member B into the chamber of member A and therethrough into and through tubular extension 0 of member G into pipe or conduit P, with said tubular extension 0 forwardly disposed at an angle approximately of 45 relatively to bosses Z). Should it, on the other hand, be desired to employ or use my new pipe-cap or fitting in connection with a horizontally-disposed service conduit or pipe, as, for instance, conduit or pipe P, see Fig. 3, then plate member C and member A are similarly detachably fastened together, but with said tubular extension 0 of member C rearwardly disposed at approximately the same angle to said inlets or perforated bosses b. It will thus be clearly evident that members A and C are reversible through a half circle or are of 180 relatively to each other and that hence my new pipe-cap may be easily interchangeably arranged or mounted either on a horizontally or a vertically dis posed service conduit or pipe, outlets or perforated bosses 6 being outwardly and downwardly presented at an angle and convexed wall 1 of member A being uppermost when my new pipe-cap is fitted upon either of said service-conduits or pipes, whereby water or rain easily sheds therefrom and is prevented from entering the service conduits or pipes.

It will be observed that member C, when fastened to member A as described, provides or forms not only a retaining member for member B and a closure for the otherwise open side of the chamber of member A, but also a supporting member for the pipe-cap as a whole. So that no sharp angles or corners may be presented to wires N by member C and its tubular extension or inlet a, the material of member C is preferably cut away or rounded at the inner end of extension 0, as at c and 0, see particularly Figs. 2 and 3.

It will be seen that my new pipe-cap fulfils in every respect the objects hereinbefore stated, and it is to be understood that changes in the form, construction, arrange ment, and combination in the several parts thereof may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
